Hi Jurian,
Thanks for the response.
I like your proposal a lot. And actually I have thought about using Db_Table
and some caching mechanisme for these purposes too. But to tell you the
truth, I'm a bit apprehensive about how to exactly implement it. Especially
because from the documentation I wasn't too sure how to implement the
relationships for Db_Table for the MySql innoDB engine.
The docs state:
"Skip declaration of $_dependentTables if you use referential integrity
constraints in the RDBMS server to implement cascading operations";
But because of this statement, I'm a bit unsure of what I *do* need to
define in order to fully profit form Db_Table's relationship management and
profit from innoDB's cascading operations at the same time.
So basically my next question is:
How would I define relationships in Db_Table for innoDB tables without it
conflicting with each other. If you, or somebody else could elaborate on
this for me, I would much appreciate it.
Concerning cache: I absolutely need to dig in to this soon too, because I
really want to start taking advantage of caching. I haven't found the time
to dig into it yet though.
One question about cache that immediately pops up in my mind though is:
Zend_Cache docs speak of frontend and backend. What do these concepts refer
to? Is this as straightforward as I think it is: frontend is where you cache
stuff for your applications frontend and backend is where you cache stuff
for your application backend? Or am I missing something vital here?
Thanks in advance for any insights.
Cheers
